              MPLS Transport Profile (MPLS-TP) Identifiers

Abstract

   This document specifies an initial set of identifiers to be used in
   the Transport Profile of Multiprotocol Label Switching (MPLS-TP).
   The MPLS-TP requirements (RFC 5654) require that the elements and
   objects in an MPLS-TP environment are able to be configured and
   managed without a control plane.  In such an environment, many
   conventions for defining identifiers are possible.  This document
   defines identifiers for MPLS-TP management and Operations,
   Administration, and Maintenance (OAM) functions compatible with IP/
   MPLS conventions.

   This document is a product of a joint Internet Engineering Task Force
   (IETF) / International Telecommunication Union Telecommunication
   Standardization Sector (ITU-T) effort to include an MPLS Transport
   Profile within the IETF MPLS and Pseudowire Emulation Edge-to-Edge
   (PWE3) architectures to support the capabilities and functionalities
   of a packet transport network as defined by the ITU-T.
